How does it work?

Nothing is ever synced between computers. Underneath the virtual disk is FolderNet's network filesystem that downloads individual files (or parts of large files) just in time when you open them.

Example 1: Photo gallery

When you open a photo stored on another computer, FolderNet fetches the file (and only this file) from the remote computer just in time for you to view it. The local copy is forgotten when you are done with it.

Example 2: Movie playback

When you play a movie stored on another computer, FolderNet fetches first few seconds of the movie and lets you watch it instantly. It will then continue downloading the movie as you watch it, staying a few seconds ahead of the playback.

Getting started

FolderNet is a free service. Just setup FolderNet app on two or more computers. It takes only a minute.

1. Create an account.2. Login on other computers.3. Choose folders to share.4. Or pick any other folder.5. Confirm folder settings.6. All set on Windows 10...7. Or Windows 7...8. Or Windows 8.1!

After the setup, you can see FolderNet virtual disk listed next to your local disk.

Every computer is represented by a folder. Offline computers are not listed.

Shared folders appear under the computer where they are stored.

Files appear to be on your computer, but FolderNet downloads only data you actually use.

Why FolderNet?

Size doesn't matter

FolderNet has no size limits for either shared folders or individual files. At the same time, FolderNet lets you access this unlimited amount of data even from computers with limited disk space. This is possible because FolderNet never syncs anything. It downloads data just in time when you access it.

Fast and light on Internet data

FolderNet attempts to make direct connection between computers whenever possible before resorting to relay server. Under normal circumstances, most data is transferred over WiFi or regional networks, which improves speed and saves bandwidth.

Distance doesn't matter

Contrary to traditional network filesystems, FolderNet is designed to work over the Internet. It traverses firewalls, home routers, mobile networks, and IPv6 networks. It will maintain high throughput even over long distances as far as the underlying network allows it.

Secure and private

FolderNet is a zero-knowledge system. Our cloud servers cannot see the content or names of your files. All communication between your computers is encrypted and authenticated with your password, which is never sent to the cloud.
